IMPROVEMENT IN PUMPS.

Speciiication forming part of Letters Patent No. 118,222, dated August22, 1871 g antedated August 1H, 1871.

To all whom it may concern:

Be it known that we, JACOB EDsON, of Boston, in the. county of Suffolk,and PERSON NOYEs, of Lowell, in the county of Middlesex, both in theState of Massachusetts, have invented certain new and usefulImprovements in Pumps, ofwhich 4the following' is a full, clear, andexact description,

reference being had to the accompanying drawing making' part of thisspecification, in which- Figure l represents a front elevation of ourimprovement as applied to an oil-tank and cabinet. Fig. 2 represents atransverse section on the dotted line A B of Fig. l. Fig. 3 represents avertical sectional elevation; and Fig. 4 an end view, with parts notshown in the other iigures.

This invention relates to pumps which have a reciprocating `gnotion, andwhich are used for raising liquids from a storing-tank below to areceiver or measuring-fountain, or for drawing liquids from casks andemptying the same into the storing-tank, by means of connecting` anddisconnecting-tubes or pipes and other apparatus hereinafter described.This invention has for its object to furnish and combine in a singleinstrument a reciprocating lifting-pump, a selfcharging pump, and asiphon-pump, capable, by means of connecting-tubes, of bein g transformed into a siphon, and draw liquid from a cask above the storing-tankinto the latter without working the pump, and, by means of otherconnectingtubes, of pumping liquid from a cask on the same level withthe tank and emptying it into the latter, and of measuring the liquidduring the process.

In the said drawing, A represents an ordinary tank used for storing oil,and above this tank a case or cabinet, B, of any common form. In onepart of the said case we secure the pump, the upper end of which risesto within a fountain, C, furnished with a return-pipe, a, no higher thanthe pump. rllhe upper pump-box e is of common construction, and operatesabove the lower box by a lever in the usual way; but the lever or handleb of the pump is connected to the side of the fountain by a ball-jointand ears projecting from a plate. The ball c, being formed at thejunction of the lever and the handle, fits a corresponding recess in theplate n and the side of the fountain, protruding from both sides, thusforming a convenient connection and nearly closing the aperture throughthe side of the fountain,

and measurably preventing the passage of oil, which sometimes spurtsthrough the opening around the handle connected by the usual old method.At a suitable distance below the reciprocating upper pump-box is avalve-seat, d, and on this is seated a valve, h, having a dependingbalance-rod, g, surrounded by a tube, j', which extends to near theclosed bottom end of the pump-tube. This tube j" connects with thevalveseat, and is open at both ends. At one side of the pump-tube, andbetween its lower closed end and the lower valve-seat, is a side inlet,fm, or connection, formed by a quarter-turn connection, and to the lowerend of this is coupled or connected the draught-tube D leading to thestoringtank. At one side of this connection m is a side port, fi, whichis closed by a movable cap or plug,

At or near the junction of the connection m and the draught-tube astop-valve, o, is convenient for closing the passage between the pumpand the storing-tank when pumping or drawing oil from the cask, andprevents the necessity of uncoupling the draught-tube. At one side ofthe fountain we arrange an indicator and measuringgauge, K, to show theheight and measurement of oil in the fountain. At the front side of thefountain is a faucet, p, for drawing off oil into cans or measures.

Our invention is intended for pumping kerosene and similar oils, thenature of which renders it very difcult or quite impossible to constructa pump which will not run down or leak oil so as to require rechargingevery few hours or less. 4

The operation of our improved pump is as follows: In pumping oil fromthe storing-tank with the parts connected, as shown in Figs. l and 3,the pump being charged with the liquid, the oil is drawn through thedraught-tube D and the open connection m into the pump-tube below thelower Valve, passing downward below the tube f, thence upward throughsaid tube, raising and passing the lower valve to the space below theupperbox e, andthrough this over the top of the pumpgand into thefountain. When the pump ceases to operate the oil soon runs down, which,in ordinary pumps, require recharging, but in this a sufficient quantityof oil to charge the pump is left in the lower part of the pump-tubebelow the inlet m and around the lower portion of the tube j'. With thepump in the above-described condition the upper boX is set in motion bythe usual movement of the handle. The

charging oil is first raised into the space above the valve h and aroundthe upper and movable boX sufficient to charge the pump and make it drawfrom the tank or from a cask outside of the tank; and this charging oilis always left in the lower part of the puinp-tube ready for use whenrequired. In pumping oil from a cask to the storing-tank thedraught-tube D is disconnected, and a flexible tube, E, applied to thelower end of the connection m and to a cask, G, on the same level withthe tank, as clearly shown in Fig. 4. With this arr. ngement the oilfrom the cask is pumped up into Vthe fountain and drawn off through thefaucet into a pan or sink, H, beneath it, and passes through astrainer-covered aperture into the storing-tank, to be pumped up afterdetachin g and making the connections, as shown in Fig. 3. In drawingoil from a cask above the storing-tank, as where the tank is located inthe cellar or room below the pump, the cask is placed in about theposition of that seen at M, in Fig.

4. In this case the draught-tube D remains connected, as in Fig. 3, andthe cap q is removed and one end of a flexible pipe applied to the sideport, and the opposite end of said tube inserted in the bung of the caskM; the valve o is opened, the pump started and worked sufficiently tofill the tubes, when the pump may cease working', and the oil may runfrom the cask M into the tank through the tube N and the side port tothe pump-tube below the lower valve h through the connection m and thedraught-tube, which together form a perfect siphon. By connecting theupper end of the tube E with the side port z' andl closing thestop-valve o at the upper end of the draught-pipe D, oil may be pumpedfrom a lower cask, Gr, and emptied into the tank through the fountainand the faucet without disturbing the draught-pipe. When thedraught-pipe is detached or disconnected it falls a short distance, andwould strike the inner lining of the tank, and would be liable to breakthe lining and cause a leak. To guard against this liability we providea cushion or bed-plate, L, which covers the whole bottom lining of thetank and protects it from any injury of the falling disconnecteddraught-pipe inserted in any part ofthe tank.

We have referred to the side inlet m between. the lower valve-seat andthe lower closed end of the pump-tube. Above this side inlet, andsurrounding the tube f, we provide a vacuumchamber, S, which serves thesame purpose of an air-chamber below the piston in an ordinary pump; andbeside this it enables us to employ a smaller draught-tube, andconsequently to work the pump more rapidly. It insures a uniform an dregular draught and iiow of oil through and from the pump into thefountain, leaving the o il unagitated against the surface of themeasuringgauge and around the upper end of the returntube. Thisvacuum-chamber S, being necessarily always filled with air, exerts anassisting influence when starting` the pump, or aids the charging oil inthe lower part of the pump-tube in drawing the oil from the tank. Thebed-plate L, before referred to, is not intended as a mere fender toprevent the detached draught-tube;

Abut this bed-plate serves another and a very important purpose, whichis as follows: After the tank has been several times filled withkerosene oil, and as many times emptied or partially emptied of itscontents, a considerable quantity of sticky, pasty, sedimentarysubstance will be found upon the bottom. To remove this sedimentarydeposit from the bottom of the tank, after the oil is pumped'out, we areobliged to use both a scraper and ashovel or similar instrument, which,if used with the utmost care, are liable to injure the bottom lining.This bedplate L, covering the entire surface of the bottom of the tank,receives the deposit before mentioned, which may be removed from thebed-plate without injury to the tank-linin g. This bed-plate also servesa third purpose of protecting the whole of the bottom lining', and notmerely that portion under the draught-tube; and this is important, as itis necessary at times to remove the pump from one part of the tank toanothersometimes a short distance, and at other times nearly the wholelength or width of the tank; and such a removal of the pump is generallymade to accommodate some counter, desk, or fixture in the store, or tobring the pump on the opposite side of some partition or ewall, the tankbeing in the cellar; and this obviates the necessity of moving the tank,which, if full, would first have to be emptied of its contents,involving considerable labor and delay. Thus it will be seen that thebed-plate L serves a threefold purpose, and is of considerable advantagein connection with the pump.

In this case we make no claim for the storingtank, or the case orcabinet above the tank, or for a standing fountain, or an indicatortherewith connected, such parts being embraced in the former patent orpatents to lEnsoN N oYEs 5 but We claim as our inventionl. Aself-charging pump, substantially as described, consisting of an outerpump-tube, an inner tube, j', valve-seat d, and valve h, and providedwith a connection or inlet, m, having a side port, 1l, a cap, q, adraught-pipe, D, an upper box, e, and an operating-lever, all combined,arranged, and operating substantially in the manner and for the purposeset forth.

2. The combination of all the parts, viz., the

pump and the cabinet B, the fountain C, returntube a., the gauge lc,faucet p, sink H, exible tube E or N, bed-plate L, and tank A, allarranged to effect the objects herein set forth.
